Something a friend shared with me:
I don't know that I think teaching is the greatest art, but it certainly is one. And, as is true of most arts, visual, performing and otherwise, it goes through phases and fads and styles. Some of these differences are esthetic and not necessarily able to be ranked. Is Impressionism better than Cubism? Now? But, cramming 10 kids of different ages into a too-small room, with slates and bad chalk, and making them only memorize the same thing irrespective of skill level is probably not as good as other options.
When I started it was all about "imparting information" and making students "as smart as possible". Things have changed. I do remember when the "new pedagogy" started, I instituted some small group/peer interactions in a human embryology course I was teaching. I had several individual and sets of students (class was about 60) come to me and say "we do not care what our peers have to say, we only want you to give us more facts and information". Sigh. I worked at it.
I now teach in a medical school. We have pretty rigid standards about what to teach, as a function of board exams. But slides & strategies that I had used for years are not acceptable. I had always thought that students learned better when they actually wrote things down as well as heard and read them. But, my reviews have always turned up a few "Dr. Theron expects us to write a lot and its difficult to do so accurately". Of late, they have turned into "Dr. Theron expects us to take notes in her lecture, and I don't think I should have to". So I am busy changing my lectures. I give up on this. Standards are changing. Art moves on. Me too.
